Vlax, who are you gonna believe...me, or a guy in a grass skirt!
I'd like to try one of those decade old stouts though, I bet they are incredibly smooth.
I opened a brown ale the other day that's been bottled 18 months, and it was fine. OTOH, I buy a lot of beer in flip-tops (to add to my bottle supply,) and have frequently come across flat/oxidized bottles.
I suppose there isn't any kind of cap that is 100% reliable for long-term aging. Still, I'd be inclined to trust a synthetic cork more than a flip-top. It would be a drag to open up the anniversary mead in 20 years and find it spoiled.
